OK - two sides to the coin.
Side 1: What are they smoking with these things, are people really going to pay those prices? $69 to ride 3 rides for an hour? That's completely nuts. No way I would ever do it.
Side 2: I just don't get why people are freaking out about these things. If you don't do it, it should have NO effect on you.
#1: They do NOT mean the end of EMH. In both the case of the Extra evening and extra morning ticket - they are in ADDITION to EMH. They only do morning and evening EMH once a week in MK. There are plenty of other days to schedule this event. Much like the old E-ticket evenings, which of course were much cheaper but were a paid event. There NO reason to assume it's the end of EMH. They use EMH to drive people to stay on site, they will not take it away.
#2: They aren't taking away hours from regular paying customers. These are EXTRA hours, both on the evenings (after 10 or 11 PM) and mornings (before 9 AM).
They haven't done the rope drop morning show on EMH mornings in ages. In this case, they will probably continue to do it at the regular time even on these mornings - its no different from the people coming for ADRS.
#3: Why would you think there will be long lines at 9 AM for these two rides? First off - there won't be a lot of people that pay this. Second - the people that pay this will have already RIDDEN these 3 rides by 9 AM - likely multiple times. At 9 AM they will be moving on to OTHER rides.
It's idiotic, but not something to decide "I hate Disney!" over.
